To, all whom it may concern:

' Be it known that I, FELIX KARMELI, a subject of the Emperor ofAustria-Hungary, residing at Vienna, Austria-Hungary, have inventedcertain new and useful Improvements inMotor-Vehicles, of which thefollowing is a specification.

This invention relates to an improved construction in motor vehicles orcycles in which there is arranged centrally within a runningwheel afiywheel surrounded by a casing,

, the fly-wheel being situated in the middle plane ofthe running-wheeland free to be rotated independently thereof by means of laterallyarranged motors which act directly upon the axis of the flywheel.- Therotation of this axis is transmitted through toothed;

gearing to frictional gears of different diameters and speeds ofrotation. 'The said friction-gears are capable of engagement with theinner surface of a friction-ring which is connected to the running-wheeland the flywheel casing and which serves'also as brake By throwing intoengagement the one or the other of the friction-gearsthe run-;ning-wheel whose tubular axis is mounted loose on the fiy-wheel axis canbe driven at? a greater or less speed, while after disengage, ment ofboth the friction-gears the running-.

wheel.

wheel can be at once brought to a standstill by braking without stoppingthe motors and the fly-wheel. The above-described construction can beapplied to only one running-wheel of a motor vehicle or cycle or to bothor all the running-wheels. With two-wheeled motor-cycles the stabilityand safety in running are increased by the provision of a shiftablesupporting device provided with rollers which in the lowered positioncome in contact withthe tion, on line E F, Fig. 2.

Fig. 6showsaconstruction of the lever mechanism for throwing the iric- 1g. 7shows to a smaller scale a complete side View of a two-wheeledmotor-cycle construct- Fig. 8 shows a plan of the shiftable supportingdevice with the runningrollers. Fig. 9 shows a side view of thesupporting device to a larger scale.

wheel 1 is arranged centrally in the middle plane of the running-wheel.It is surrounded by a divided casing 2, in the bosses 3 of which theaxis 41 of the fly-wheel is freely rotatable. The fly-wheel casing isfixed toa ring 5, which isconnected by the wheel-spokes with thewheel-rim, provided with a pneumatic tire 6. or the like, or the ring 5might itself be made to constitute the wheel-rim. The running-wheel ismounted upon the bosses of the fly-wheel casing, the ball-bearingsthereof being situated in recesses in the sides of the casings 7-mounted on the'cycle-frame.

Upon the casings 7 are mounted on each side of the running-wheel themotor-cylinders 8,

- the pistons of which are connected by connecting-rods 9 to cranks 10,keyed upon the flywheel axis i, so as to effect the rotation of theflywheel. Toothed pinions 11, fixed on each end of the fly-wheel axis,engage with toothed wheels 12, Figs. 3 to 5, which transmit the motionthrough toothed wheels 13 to toothed wheels 14 and 15 of differentdiameters, whereby friction-gears 16 16 and 17 17,

fixed on the axes of 14 and 15, are rotated at different speeds. Thetoothed wheels 14: and 15 on each side are-mounted in divided casings18, which are shiftably mounted on rings 19, Figs. 2 and 5, projectingfrom the inner side of the casings 7 and surrounding the toothed wheels13. Each casing 18 is connected, by means of a rod 20, in any suitablemanner with a regulating-lever 21, Fig. 6, ad justably mounted on themotorcycle, by means of which the casings 18 can be shifted on thebefore-mentioned ring, so as to bring the one or other pair offriction-gears 16 or 17 alternately in engagement with the inner surfaceof the ring 5. In the position of the friction-gears 16 and 17 shown atFig. 2 neither of these are in engagement with the As will be seen fromFigs. 1 to 3, the flyring 5 of the running-wheel, so that the rotationof the fly-wheel will not impart any motion to the running-wheel; but assoon as either of the friction-gears 16 or 17 is brought into engagementwith the ring 5, as shown at Fig. 4:, the fly-wheel axis will drive therunning-wheel with a corresponding greater or less speed.

The starting of the motors that is to say, the rotation of the fly-wheelaxis-can be effected, as is usual with motor-cars, by the rotation of acrank-handle 22, Figs. 1, 2, and 3, which is temporarily mounted on theaxis of one of the toothed wheels 12. The outer circumference of thering 5 is arranged for the reception of a band-brake or other form ofbrake in the usual manner, whereby it is rendered possible afterthrowing the frictiongears out of engagement to bring the running-wheelat once to a standstill, notwithstanding the continued motion of themotors and the fly-wheel.

For increasing the stability and safety in running, the two-wheeledmotor of the abovedescribed construction is provided with a supportingdevice 23, which is preferably arranged to pivot on the axis of therunningwheel and which carries running-rollers 24, situated on each sideof the running-wheel, as shown at Figs. 7 to 9. This supporting devicecan be raised or lowered and is for this purpose provided with anarc-shaped bar 25, Fig. 9, which can slide in the curved rear tubularbar 26 of the motor-frame and which is subject to the action of a spring27. By means of a movable catch 28, which engages with one or other ofthe notches 29 and 30 of the bar 25, the supporting device can be fixedeither in the raised or the lowered position. If the catch 28 bewithdrawn by a suitable lever device when the support is in the raisedposition shown at Fig. 7, the latter can be pressed down by means of apedal, as shown at 23, so as to bring the running-rollers on the ground,as at Fig.9, the spring 27 being then put in tension. In this positionthe supporting device will be locked by the catch 28 engaging with thenotch 29. On withdrawing the catch the supporting device will be broughtback into the raised position by means of the spring 27 This arrangementenables the rider to bring the motor-cycle to a standstill with thesupporting device lowered and also to start it again without thenecessity of dismounting.
